Trading halts and circuit breakers — how long do halts last in the stock market

Short lead

The phrase "how long do halts last stock market" refers to pauses in trading that exchanges or regulators put in place for single securities or for entire markets. In this guide you will learn the common types of halts used in U.S. markets, the concrete rules that set durations, what happens to orders and prices during a pause, and how traders and investors can prepare. As of 2024-06-01, according to Investor.gov and SEC guidance, the U.S. uses a combination of market-wide circuit breakers and single-security mechanisms (like Limit Up–Limit Down) to manage extreme moves and news events.

Note: while most of this article focuses on U.S. stock-market rules, other jurisdictions and crypto platforms (including Bitget for crypto trading) have their own pause policies and timescales.

Overview

Trading halts and circuit breakers are tools exchanges and regulators use to preserve fair, orderly markets. They exist to:

• Give the market time to absorb material company news and prevent uninformed, rapid trading.
• Calm extreme, fast-moving price volatility that may not reflect available information.
• Allow technical or operational issues to be diagnosed and fixed without trades occurring at erroneous prices.
• Protect investors from trading in markets where reliable quotes or liquidity are not available.

When people ask "how long do halts last stock market," they are usually seeking the specific durations or rules that determine how long a pause will be in effect. Different halt types have different triggers and concrete timing rules. This article walks through those types and the typical durations you will encounter.

Types of halts and pauses

There are several distinct types of halts and pauses. Understanding each helps answer "how long do halts last stock market" in context.

Market-wide circuit breakers

Market-wide circuit breakers are coordinated pauses that suspend trading across multiple exchanges and instruments. In the U.S., they are tied to standardized percentage declines in the S&P 500 index. The goal is to curb panic selling and give market participants time to reassess prices and information.

Key features:

• Triggered by S&P 500 declines measured from the prior day's close.
• Implemented across equity markets to ensure coordinated reprieve from extreme selling.
• Have predefined time-based consequences (see the durations section below).

When investors ask "how long do halts last stock market" in reference to market-wide events, they are usually referring to these S&P 500-based pauses.

Single-security circuit breakers (Limit Up–Limit Down, LULD)

Single-security circuit breakers are designed to prevent trades at prices far from a reference or fair value. In the U.S., this is largely governed by the Limit Up–Limit Down (LULD) Plan.

Core elements:

• A price band is calculated around a reference price; if quotes move to the band edge, a quote test begins.
• If the security's best bid or offer remains at the band edge after a 15-second quote-exposure period, a volatility pause (a temporary trading pause) is triggered.
• A typical volatility pause following the 15-second quote test is a five-minute pause in execution for that security. After the pause, mechanisms like reopening auctions or continuous trading resume under new bands.

When someone asks "how long do halts last stock market" for a single stock, the LULD rules are a primary determinant.

News-pending or regulatory halts for individual securities

Exchanges or regulators can halt a single security when a company has material, nonpublic information pending disclosure. These "news-pending" halts are intended to give the company time to release the information and investors time to read it before trading resumes.

Typical characteristics:

• Initiated by exchange staff or a regulator (e.g., FINRA) when a significant corporate announcement is expected or in process.
• Duration depends on how quickly the issuer provides clear, public information and how the exchange determines market conditions are appropriate for resumption.

Questions about "how long do halts last stock market" in this category usually have variable answers: many are short (minutes) but they can be longer depending on circumstances.

Non-regulatory halts and order-imbalance pauses

Exchanges sometimes pause trading to manage large order imbalances at the open or to address technical issues. These pauses are not necessarily related to company news or formal regulatory action but are used to establish fair opening prices and avoid disorderly trades.

Examples:

• Pre-market or opening imbalance calls to collect buy and sell interest and run an opening auction.
• Pauses to resolve an exchange's routing or matching system issues.

Durations are situation-dependent; they are often short but could extend if the underlying problem persists.

Trading suspensions

Trading suspensions are more severe, formal steps that often follow regulatory review. The SEC can suspend trading in a security if there are concerns about a company’s public information, potential manipulation, or other public-interest reasons.

Characteristics:

• Suspensions can last days, weeks, or months until disclosure or compliance issues are resolved.
• They are distinct from temporary exchange halts and usually indicate deeper regulatory or listing concerns.

When the question is "how long do halts last stock market" and the halt is actually a suspension, expect much longer durations than a typical exchange-imposed pause.

Typical durations — concrete rules and common practice

This section addresses specific timing rules so you can answer "how long do halts last stock market" for each common halt type.

Market-wide circuit breaker durations

U.S. market-wide circuit breakers are based on percentage drops in the S&P 500 from the previous close. The current standard thresholds are:

• Level 1: 7% decline → 15-minute trading halt if triggered before 3:25 p.m. ET that day.
• Level 2: 13% decline → 15-minute trading halt if triggered before 3:25 p.m. ET that day.
• Level 3: 20% decline → halt for the remainder of the trading day, regardless of time of day.

As of 2024-06-01, these thresholds and timing rules are the principal framework used in the U.S. (Investor.gov / SEC guidance). When people ask "how long do halts last stock market" after a broad sell-off, these predefined timeouts are the answer for market-wide events.

LULD / single-stock volatility pause durations

The Limit Up–Limit Down (LULD) Plan governs single-stock volatility pauses. Key timing rules related to the question "how long do halts last stock market" for single stocks are:

• When a security’s price moves to the upper or lower LULD band, a 15-second quote-exposure test begins.
• If the best bid or offer remains at the band edge after the 15-second window and the quote is not executable at an incremental price improvement, a five-minute trading pause is typically triggered.
• After the pause, the security reopens with updated price bands and may use opening or reopening auction processes.

Bands themselves vary by security tier and share price; lower-priced or less liquid securities often have wider or floating bands.

News-pending and regulatory halts

Exchange-initiated halts for pending news have no single fixed duration. Common practices include:

• Short halts of several minutes to allow a press release or regulatory filing to be made public and disseminated.
• Longer halts if the company or regulator needs time to prepare, verify, or supplement disclosures.

Exchanges generally reopen a security only after they are satisfied information is public and the market can trade fairly; thus, answers to "how long do halts last stock market" in these cases range from a few minutes to hours.

Non-regulatory and technical halts

When halts are due to technical or operational problems, durations depend on the severity of the issue:

• Minor routing or matching errors may cause minute-level pauses.
• Systemic problems or connectivity failures can lead to multi-hour outages; in exceptional cases the exchange may remain closed for trading in affected instruments until the next trading day.

In such contexts, the question "how long do halts last stock market" depends entirely on problem resolution time.

Trading suspensions and prolonged halts

Regulatory suspensions—often initiated by the SEC or exchanges for public-interest reasons—can last much longer than exchange halts:

• Suspensions may last until required disclosures are made, financial restatements are completed, or other compliance problems are resolved.
• Days, weeks, or months are possible, and in severe cases the security may be delisted.

When the query refers to such a suspension, the expected answer to "how long do halts last stock market" is: indeterminate until the underlying issues are fixed.

What happens during a halt

Understanding market mechanics during a halt answers follow-up questions about order handling and price discovery.

• Order entry: In many exchange halts, brokers may accept and queue new orders, but executions are not processed until trading resumes. The rules for order handling (e.g., whether day orders remain valid) depend on each exchange and broker.
• Quotes: Public quotation may be capped or removed for the halted security. Market data feeds will typically show a halt status and remove continuous trade prints.
• Opening/reopening procedures: Exchanges often use an auction process to establish a reopening price once conditions permit. These auctions collect buy and sell interest and determine a single crossing price that maximizes executable volume while respecting limits such as LULD bands.
• Dissemination: Exchanges issue halt reason codes and status updates so traders and brokers can monitor the situation (see the Appendix for common codes).

Brokerage platforms differ in how they present halts and what orders they allow during a pause. If you are asking "how long do halts last stock market" because a position is halted, check your broker’s guidance for order behavior during halts.

How halts affect price behavior and orders when trading resumes

Trading often resumes with notable effects on price and order fills. Key points:

• Price gaps: Reopening prices can gap up or down relative to the last trade before the halt. Auctions and pent-up order flow drive these moves.
• Limit vs market orders: Market orders at the moment of reopening may fill at prices far from the pre-halt level; limit orders protect against unwanted fills but may not execute if the market jumps past the limit.
• Volatility: Resumption can bring concentrated volatility as liquidity providers, algorithmic traders, and human traders interact with imbalanced book conditions.
• Order cancellations: Some participants cancel stale orders during a halt. Brokers may also automatically cancel or modify certain order types based on their policies.

When wondering "how long do halts last stock market," it is helpful to also plan for the immediate minutes after resumption when execution risk is often highest.

How to prepare and manage positions

Practical steps to manage your positions around halts and to respond to the question "how long do halts last stock market":

• Monitor official halt notices: Exchanges and market regulators publish halt reasons and status updates. Keep an eye on exchange status feeds or your broker’s alerts.
• Review company news: For news-pending halts, monitor the issuer’s regulatory filings and press releases to anticipate timing.
• Use limit orders when possible: Limit orders can prevent fills at unexpected prices when trading resumes.
• Avoid relying on market orders at reopening: Market orders can execute at extreme prices in volatile re-openings.
• Consider staggered position management: If you’re a trader, plan entry and exit strategies that account for potential pauses and the five-minute LULD pause rule.
• Know your broker’s policies: Different brokers and platforms handle halts, queued orders, and auction participation differently.

These measures address both the practical and informational aspects of asking "how long do halts last stock market." Preparation reduces execution surprises.

Regulatory framework and responsible bodies

Several bodies and rules govern halts and circuit breakers in U.S. markets:

• The SEC (Securities and Exchange Commission): Oversees market structure and enforces trading suspension or public-interest actions.
• Exchanges (NYSE, Nasdaq, regional exchanges): Implement and operate halts for single securities and communicate halt codes.
• FINRA: Oversees broker-dealer conduct and has a role in halting OTC securities.
• Limit Up–Limit Down Plan Administrator: Implements and administers the LULD Plan for single-stock volatility pauses.
• Investor education outlets (Investor.gov): Provide plain-language summaries of circuit breakers and investor-facing guidance.

When answering "how long do halts last stock market," citing the responsible body helps clarify whether the pause is an exchange action, a LULD mechanism, or a regulatory suspension.

Where to find current and historical halt information

To find up-to-date halt notices and historical records, consult the following official sources:

• Exchange status pages and market operations notices (e.g., NYSE and Nasdaq trader updates).
• FINRA trading halt notices for OTC and certain exchange-listed securities.
• SEC / Investor.gov materials explaining market-wide circuit breakers and investor guidance.
• Broker-dealer platforms (your broker or trading venue) for real-time alerts and order status.

These sources will answer both "why was this security halted?" and "how long do halts last stock market" in specific instances.

International and crypto-exchange differences

Other countries use different thresholds, bands, and procedures for halts. Rules vary by jurisdiction and exchange.

In crypto markets, exchanges apply their own pause and rate-limiting mechanisms. These are not standardized and may differ widely between venues. If you trade crypto on Bitget, for example, check Bitget’s own policy pages and announcements for how and when the platform may pause trading or withdrawals. Cryptomarkets may impose short exchange-level freezes or longer restrictions depending on the issue.

Because the question "how long do halts last stock market" usually references regulated equity markets, be aware that crypto pause policies are platform-specific rather than governed by a single national regulator.

History and notable examples

Understanding past uses of halts and circuit breakers helps frame expectations about duration and purpose.

• Origins: Market-wide circuit breakers were developed after major market disruptions (notably the 1987 crash) and have been refined to provide structured pauses in extreme sell-offs.
• March 2020: During the COVID-19 market turmoil, U.S. market-wide circuit breakers were triggered multiple times in March 2020. These activations demonstrated how Level 1/2 halts provide temporary 15-minute cooling-off windows before trading resumes (see SEC/Investor.gov historical summaries).
• High-volatility single-stock halts: The meme-stock episodes (e.g., heightened trading activity in certain names) produced many single-security halts under LULD and exchange-news pending rules. These halts varied from minutes to extended suspensions depending on disclosure and market conditions.

These episodes are concrete instances where traders asked "how long do halts last stock market" and had to respond to real-time, variable halts.

Appendix — common halt codes and terminology

Brief definitions to help decode exchange halt notices (names come from common exchange practice and Nasdaq halt-code conventions):

• LULD: Limit Up–Limit Down — mechanism to prevent trades outside specified price bands.
• News Pending (NR): Halt for pending material news from the issuer. Reopening follows public disclosure.
• Regulatory Halt (RH): Halt ordered for regulatory reasons or at the request of a regulator.
• Technical/Operational Halt (TMO): Pause due to system issues or market data problems.
• Suspension: A formal suspension of trading typically issued by the SEC or exchange for serious disclosure or manipulation concerns.
• Opening Imbalance (OIB): Auction-related pause to resolve order imbalance at market open.

See exchange-specific lists of halt codes for the exact code values used by each market (e.g., Nasdaq Trader halt code documentation).
